` To all whom t may concern.'

' the sash fastenerv in its inoperative position,

Be it known that HrnAM C. GRAY, a citizen of .the United States, residing f at B'ucyrus, in the county of Crawford and State of Ohio, has. inventedl certa-in new and vuseful Improvements in Sash` Fasteners, of

which the following is a specification.

I The present invention is directed to im` provements in sash fasteners, and has for its primary object to provide a device of this character so' constructed that it can-"be easily installed, and when in pl'ace willbe y inconspicuous.

y further object ofthe invention is to provide a sash fastener so constructed" that it will operate to lock the upper andl lower sars'hes in closed positions, orv in partially open positions, as desired'.

Still another object of the invention is to provide a sash fastener which is-operabl'e by a vseparate key, the structure being such that the key can', when inone position, hold and upon removal of the key the fastener will automatically operate to lock the sash.

, i Afstill further object of the invention is to provide asash fastener which is constructed in a compact manner so ijtcan be appliedto the window frame without in any wa. interfering with the sash weights.

ith these and other objects in view, as will appear as thedescription proceeds, the invention consists in the novel feature of construction, combinations of elements and arrangements of parts, and hereinafter to be fully described and pointed out in the appended claims.

In the accompanying drawing:

Figure 1 is a fragmentary front elevation of a window equipped with the fastener, parts being broken away to illustrate the racks.

Figure 2 is a` vertical sectional view through one of the fasteners.

Figure 3 is a sectional view on line 3-3 olf Figure 1.`

Figure 4 is a .sectional view on line 4-4 of Figure 2. i

Figure 5 is a perspective view of the key uide. g Figure 6 is a detail perspective view of the key.

Referring to the drawing 1 and 2 desig nate, respectively, the upper and lower sashes, the upper sash having fixed to one of its side rails a rack bar 3, while thel lower sash has irxed to one of itssi-dfe` ralils a rack bar14, the teeth` ofthe rack barsv being directed in opposite directioris, the'l purpose o-f which Awill lia-tery appear obvious.- v

1n order to lock botlfr the`r u-pper and lower sashes it isnecessary of coursfe to usel two fasteners, 'but since'v these fasteners are identical 1n construction',- the description "of vone will sufficel for both'.-

' To install the fastener, one side of the window cas-ing 5I is provided with a mortice i o in which is placedV the casi-ng 7, 'saidg cas mg being preferably rectangular in shape. Formed integral with the inner face ofthe rear wall 8 of the casing is' a hollow pest L 9, and slidably engaging said 'postis'y a holt 10, said `bolt having a. bore11 formed4 longitudinally therein for receivinga portion of y the coilk spring 12, 'the other portion of which' is engaged in the hollow' post 9, there A.

bein-g a guide pin k13A located in said post'.

Thebolt 10 has riveted thereto a pair, of arms 14, said arms being disposed diametrically opposite each" otherand' upon the sides of thevbolt` 10; The free ends lof the yarms 14 terminate in lips 15, the' purpose of which there being two of these pins. '.Fhe ypins t 18 are spaced a suiiicient distance apart to permit the post 9 to lie therebetween, and since the arms 14 are located on opposite sides of the bolt 10, said pins will be in positions to engage the lips 15. 'Since the spring 12 tends to force the bolt 1() inwardly it is apparent that ythe lips 15 will yieldably engage the pins.

A rod 19 is provided, said rod being engage-d in a passage 2O formed in the window casing 5 and has its inner end fixed in any suitable manner to the adjacent end of the head 17, whereby when said rod is rotated similar movement will beimparted to the head 17 with the result that the pins 18 will be swung in a direction to slide the bolt 10 into the hollow post 9.

The outer end of the rod 19 is journaled y i disposed opposite each other, the purpose ot which will later appear.

The key 27 has a circular body 28, yand carried by the body are diametrically disposed studs 29, said body being further pro vided with spaced fingers 30, which are arn ranged upon the inner face thereof.

Since the rack bars 3 and 4 have their teeth directed in opposite directions it is obvious that either of the sashes 1 and 2 may be locked in their closed ositions or partially closed positionsy as t e occasion may require, vit being apparent that when the bolt 10 is engaged with the rack 4 that the asso- .ciated sash cannot be raised until the bolt is Withdrawn from engagement with the rack` and it will also be noted that the sash 1 cannot be lowered until the bolt is disengaged from the teeth of the associated rack.

Assuming that the bolt 10 is engaged with the teeth of the rack 4 and it is desired to raise the sash 2 it will be necessary to withdraw the bolt 10 so that the sash and associated rack can be raised, and to do this it is only necessary to place the body 28 ot the key in the collar 23 and at which time the fingers() will engage the sockets 26 carried by the disc .25. Upon rotating the key27 the bolt in its withdrawn position. It will v be ofcourse obvious that the lingers 30v are of sutlic'ient length to engage the sockets 26 to impart rotary movement to they disc 25 before the studs 29 drop into the notches 24. Upon removal of the body 28 `ot the key it will be obvious that the disc 25 can rotate in a reverse direction under the action of the spring 12 as it expands, thus placing the bolt 10 in a position to engage the teeth ot the associated rack.

What l claim is: l

1. ln a sash fastener, the combination with a casing tor attachmentl to al window trame, of a hollow post located inthe casing, a bolt slidabljvY engaged in the post, said bolt having arms carried thereby, said arms being provided with lips, a head journaled transversely in the casing and havingpins for slidably eiigagging'said lips, a rod associated with the head, and means `for rocking the` i rod to impart similar movement to the pins to cause the bolt to slide in said post.

2. ln a sash fastener, the combination with a casingfor attachment. to' a window frame, of a bolt slidably mounted in the casing, arms carried by the bolt; a head journaled transversely. in the casing, pins carried by the head for sliding engagement with the armst a rod associatedwith the head, a collar fixed to the windoiv-,

trame, a disc located in the collar and fixed to the rod, said collar havingnotches formed therein, a key having` means carried thereby .tor interlocking egagernentwith the disc to rock the rod, studs carried by the key body,

said disc being' held against reverse move ment when said studs are engaged in the' notches, whereby the belt is held in its inoperative position.

lntestiniony whereof l aiiiX my signature.
